ire States Patent 0 Referring to the drawings, which illustrate apreferred embodiment of the present invention, FIG. 1 shows the generalarrangement of the indicator mechanism, which includes a motor andclutch mechanism, generally indicated as 59, mounted on the left end ofa support frame 60, nine indicator wheels 61, mounted adjacent to theclutch mechanism, and a cam switch actuating mechanism, generallyindicated at 62, mounted on the righthand end of the support frame 60.

The remote indicator mechanism of the present invention is used inconjunction with a cash register or any other type of calculatingmachine where the results of the machine operation are required to bedisplayed. Two examples of cash registers with which the remoteindicator of the present invention may be used are disclosed in UnitedStates Letters Patent No. 2,972,422, issued to Mayo A. Goodbar et al. onFebruary 21, 1961, and in United States Letters Patent No. 3,006,538,issued to Johann I. Deutsch on October 31, 1961. Both of these cashregisters are equipped with readout switches which are mechanically setby operation of the cash register to represent the amount to bedisplayed by the remote indicator. Since the construction of the readoutswitches and their operation are fully disclosed in the above-citedpatents, their representation and disclosure will be limited to theschematic diagram of FIG. 8. As will be explained more fullyhereinafter, the various electrical controls disclosed in the presentinvention position the indicators according to the setting of thereadout switches located in the parent machine.

Referring now to FIGS. 1 and 2, there is shown mounted on the left endof the support frame 60 a side frame 63, to which an AC. drive motor 65is mounted by means of screws 64. The side frame 63 has two mountingblocks 66 attached to it by means of screws 67, the blocks being used tomount the side frame to the support frame 60 by means of screws 68. Themotor 65 has a drive shaft 69, which projects through the side frame 63and has pinned to its end a drive pinion 70 (FIG. 2). Journaled in theside frame 63 is one end of an indicator drive shaft 71, the other endof which is rotatably supported by a side frame 72, mounted on theright-hand end of the support frame 60 in a manner similar to the sideframe 63. A bronze bushing 73, mounted on the side frame 63,accommodates the end of the indicator shaft 71. Loosely positioned onthe left end of the indicator shaft is a gear assembly for driving saidindicator shaft. This assembly includes a control gear 74 secured on thehub of a ratchet wheel (FIG. 2). Positioned between the control gear 74and the bushing 73 is a spacer 76. The control gear 74 engages and isdriven by the drive pinion 70. It will be seen from this constructionthat, upon operation of the motor 65, both the ratchet wheel 75 and thecontrol gear 74 will be driven.

Associated with the ratchet wheel 75 is a clutch ratchet pawl 77 (FIGS.1 and 2), rotatably mounted on a disc 78, which in turn has a hubportion 83 pinned to the indicator shaft 71. As may best be seen fromFIG. 2, the disc 78 is provided with a slot 79 and a stud 80, to whichis attached one end of a spring 81. The other end of the spring 31 isattached to a stud 82, mounted on the clutch pawl 77. With thisarrangement, the spring 81 normally urges the clutch pawl 77 in such adirection as to bring it into engagement with the ratchet wheel 75.

Loosely mounted on the indicator shaft 71 adjacent to the disc 7 8 is aplate 84, on which is mounted a stop stud 85, which projects through theslot 79 of the disc 78 (FIG. 1). The end of the stop stud 85 ispositioned adjacent to and in engagement with a flange 86 of the ratchetpawl 77, thereby normally preventing the ratchet pawl 77 from movingclockwise under the urging of the spring 81, as viewed in FIG. 2, toengage the ratchet wheel 75. The plate 84 also has a notch 37 (FIG. 2),located on its edge, into which is positioned one end of a control pawl83. The other end of the control pawl contains a slot $9 (FIG. 2), intowhich is positioned a pin 90, mounted on the end of a plunger 91 of aclutch control solenoid L1, mounted on the support frame 611. Thecontrol pawl 58 is rotatably mounted on a second control pawl 93, whichin turn is rotatably mounted on a stud 94 (FIG. 2) supported by the sideframe 63. The control pawl 93 has, mounted on its end, a cam roller 95,which coacts with a cam (FIGS. 1 and 2) pinned to the indicator driveshaft 71. The cam 96 has a notch 97, into which the roller 95 of thepawl 93 is normally urged by a spring 98, mounted between a stud 99located on the pawl 93 and a stud 1% (FIGS. 1 and 2) mounted on the sideframe 63. The pawl 93 also contains a slot 101 (FIG. 2) in which ispositioned a pin 102 mounted on the control pawl 88, thus providing therotatable support for said pawl $8.

With the construction just described, energization of the solenoid L1retracts the plunger 91 against the urging of a spring 1113 mountedbetween the pin 91 on the plunger and a stud 1134 mounted on the sideframe 63. Retraction of the plunger rotates the control pawl 88clockwise as viewed in FIG. 2. This movement withdraws the pawl fromengagement with the plate 84, thereby releasing the clutch ratchet pawl77 and the plate for clockwise movement under the action of the spring81. This results in the latching of the pawl 77 with the ratchet wheel75, thereby coupling the indicator shaft 71 to the operation of themotor.

As will be explained more fully hereinafter, the motor drives theindicator shaft through two revolutions to provide an indicatoroperation, during which time the solenoid L1 is de-energized, therebyreleasing its plunger 91 to the action of the spring 103, this actionforcing the control pawl 88 into engagement with the notch 87 in theplate 84, stopping the plate 84 and the stud 85 mounted thereon.Stopping of the stud 85 forces the clutch ratchet pawl 77 to bedisengaged from the ratchet wheel due to the engagement of the stud bythe flange 86 of the ratchet pawl. Simultaneously with the engagement ofthe plate 84 by the pawl 88, the roller of the pawl 93 engages the notch97 of the cam 96, thus helping to stop the indicator shaft 71 andpreventing any rebound reaction between the stud 85 and the edge of theslot 79 in the disc 78.

Mounted on the indicator shaft 71 are nine indicator assemblies,generally indicated as 61 in FIG. 1. Since all of the assemblies are ofthe same construction, only one will be described. As shown in FIGS. 1,3, 4, and 6, each indicator assembly is composed of an index plate 11b5,mounted on a pair of support shafts 1%, with a hub member 1117 mountedbetween the index plates of each indicator assembly. Each of the supportshafts 1% is mounted between the side frames 63 and 72 (FIG. 1). Asshown in FIG. 4, the index plate has a center portion cut out with aseries of notches 1113 located on the inside peripheral edge. Associatedwith these notches is a clutch pawl assembly, which is shown in PEG. 6and which comprises a clutch pawl disc 1119 loosely mounted on theindicator shaft 71, a clutch pawl 111D pivotally mounted on the disc1159 by means of a stud 111, and a clutch wheel 112 pinned to theindicator shaft '71 adjacent the clutch pawl disc 1119. The clutch pawl11% is normally urged into engagement with a cut-out portion 113 of theclutch wheel 112 by a spring 114 mounted between a stud 115, mounted onthe clutch pawl and extending through a cut-out portion 161 of the disc1&9, and a stud 116 mounted on the clutch pawl disc 169. The clutch pawlhas a pair of fingers 117, which engage a stud 118, the end of whichprojects through a slot 119 located in the clutch pawl disc 109.

The stud 118 is mounted on the side of a stop selector plate 122, asshown in FIG. 3. The stop selector plate 122 has a plurality of teeth12?: on its peripheral edge and is mounted on a hub 124 (FIGS. 1 and 3),which in turn is loosely mounted on the indicator shaft 71. Attached tothe clutch pawl disc 109 by means of rivets 121 (FIG. 1) is an indicatorblank or drum (FIGS. 1 and 3), which has the numerals O to 9 inclusive,indicated as 92 in FIG. I, printed on its outer surface. Thus theengagement of the stud 118 by the fingers 117 of the clutch pawl 110interconnects the disc 169 and the indicator blank 12% with the selectorplate 1222, thereby providing a unitary assembly, which will havebasically the same movement.

Associated with the stop selector plate 122 is a stop pawl 125 (FIG. 3)rotatably mounted on the rear support shaft 106 and capable of beingmoved into an engaging position with any one of the teeth 123 of theselector plate 122. The lower portion of the stop pawl is attached tothe plunger 126 of a solenoid 127 mounted on a bracket 162, which inturn is secured to the support frame 60. A spring 128, attached betweena stud 129 mounted on the stop pawl 125 and a stud 139 mounted on theindex plate 105, continuously urges the stop pawl 125 clockwise, asviewed in FIG. 3, thereby moving the pawl to a non-engaging position.This movement of the stop pawl is limited by a stop 131 (FIG. 3), whichis formed from a portion of the index plate 125, as shown in FIG. 4.Coacting with the stop pawl 125 is a holding switch 163 (FIGS. 3 and 4)mounted on the bracket 152 and having a pair of contacts 164 and 165,which are operated by the stop pawl 125 through the engagement of theswitch block 166 with a stud 167 mounted on the stop pawl. It will beseen from FIG. 3 that the contacts 154, close upon the counter-clockwisemovement of the stop pawl into engagement with the plate 122, and openwhen the pawl is in its non-engaging position. The function of theswitch 163 will be described in connection with the explanation of thecontrol circuit disclosed in FIG. 8.

It will be seen from this construction that, during the time the clutchpawl 110 is in engagement with the clutch wheel 112, the remaining partsof the indicator assembly 61 are rotated by the indicator shaft 71. Ifthe solenoid 127 is energized at the appropriate time, the plunger 126moves to the right, as viewed in PEG. 3, thereby rotating the pawl 125against the action of the spring 128 into engagement with the stopselector plate 122. This action stops the selector plate 122, the stoppawl 110, and the disc 109. Both the pawl 110 and the disc 1%" arestopped by the stud 118. Stopping of the disc 169 stops the indicatorblank 1211 in a position to display the appropriate character. As theindicator shaft 71 continues its rotation, the clutch pawl 111) isforced out of engagement with the clutch wheel 112 against the action ofthe spring 114. Referring to FIG. 1, it is seen that the stud 115,located on the clutch pawl 110, will be positioned within one of thenotches 1138 of the index plate upon the disengagement of the pawl fromthe clutch wheel, thus insuring the proper positioning of the characterlocated on the indicator blank. Thus each indicator blank may beselectively positioned by the timely energization of its associatedsolenoid 127 to display the results of an operation of the parentmachine. Due to the fact that each clutch wheel 112 is pinned to theindicator shaft 71, the clutch wheels continue to rotate until all ofthe appropriate indicators have been set.

As will be described more fully hereinafter, the indicator blanks 12thare set during one revolution of the indicator shaft, at the end ofwhich the rotation of the indicator shaft is stopped. At the beginningof the next operation, after the solenoids 127 have been de-energized,

thereby allowing the stop pawls 125 to be returned to their'non-engagingposition by the action of the spring 128, the indicator shaft 71 isrotated one revolution, during which time all of the previously-setindicator assemblies 61 are picked up by the clutch wheels due to theaction of the spring 114 (FIG. 6), forcing the clutch pawls intoengagement with the clutch wheel 112. Thus, at the end of this firstrevolution of the indicator shaft, all of the indicator assemblies willbe in their home position prior to the'second revolution, during whichtime the various indicators are set by a control circuit which will nowbe described.

Referring to FIG. 8, there is shown a schematic diagram of the circuitfor controlling the operation of the solenoids 127 of each indicatorassembly. As previously disclosed, the remote indicator mechanisms ofthe present invention are used with a cash register of the typedisclosed in the previously-cited Goodbar et al. and Deutsch UnitedStates patents. Each of these cash registers is disclosed as having aplurality of readout switches which are set by operation of the machineto represent the amount to be indicated. In the case of the Goodbar etal. patent, FIGS. 4 and 7 of that patent disclose the readout switchconstruction, and, in columns 15 and 16 of the specification, there isdisclosed the setting of the readout switches by the indicator segment532. FIG. 7 of the Deutsch patent discloses a similar type of switcharrangement.

The switches RS2-RS10 inclusive indicated in FIG. 8 of the drawings aresimilar to the switches disclosed in the above-cited references. Eachswitch is representative of an amount bank located in the parentmachine. As indicated in FIG. 8, all the switches located above the line132 are mounted on the parent machine, while those switches andelectrical elements below the line are mounted on the remote indicatormechanism.

The switch SCI shown in FIG. 8 corresponds to the switch 956 disclosedin FIG. 18 of the Goodbar et al. patent, and its operation is describedin column 18 of that patent. The switch SC1 of the present invention isof the normally open type. The switch is controlled by the cam line ofthe parent machine, and its basic function is to prevent the operationof the remote indicator mechanism until the readout switches RSZ-RSIOhave been set by a machine operation of the type described in theGoodbar et al. and Deutsch patents cited previously.

The power supply as shown in FIG. 8 is of a standard design and consistsof a rectifier 133, the load resistor R1, and the filter capacitor C1,to which is applied a current from an A.C. source over the conductors134, 135. The drive motor 65 is shown connected across the conductors134, 135, which provides the motor with an energizing pulse. The A.C.source to which the conductors 134, 135 are connected is located in theparent machine. It is obvious that any type of operational arrangementof the A.C. source may be had depending upon what conditions arerequired. Thus the A.C. source may be supplied to the motor 65 and therectifier only during the operation of the parent machine or during somepart of the operation of the machine. In the present example, the A.C.will be presumed to be supplied during the operation of the parentmachine. After all of the readout switches RSZ-RSII) inclusive have hadtheir wipers set according to the data to be indicated by an operationof the parent machine, the switch SCI closes, thereby providing an A.C.energizing pulse to the clutch control solenoid L1 from the rectifier133, over the conductors 137, 138, and 139, the closed switch SC1, theconductor 140, the solenoid L1, and the conductor 168 to the other sideof the rectifier 133.

FIG. 7 is a time chart showing the operation of various cam-operatedswitches and the clutch solenoid L1 during two complete revolutions ofthe indicator drive shaft 71. As described above, the closing of theswitch SCI energizes the clutch control solenoid L1, thus latching theindicator drive shaft 71 to the drive motor 65. It will also be seenfrom FIG. 7 that the normally open switch SC2, a cam-operated switchmounted on the right side of the remote indicator mechanism, theoperation of which will be described hereinafter, closes at sixtydegrees of the first revolution of the drive shaft, thus providing analternate energizing path to the solenoid L1 over the conductor 169(FIG. 8). This arrangement allows the switch SCI to open withoutdropping out the solenoid L1, thus allowing the drive shaft 71 to berotated through two revolutions. As explained previously, during thefirst revolution of the drive shaft 71 all of the indicator assembliesthat were actuated during the previous operation are picked up by theaction of the spring 114 of each indicator assembly urging itsassociated clutch pawl into engagement with the cut-out portion 113 ofthe clutch wheel 112 as the clutch wheel rotates with the drive shaft71.

In order to control the positioning of the various indicator assemblies,two timing switches, a normally open switch 8C3, and a normally closedswitch SC4, each controlled by the operation of the indicator driveshaft, are used in conjunction with a three-level control switch RS1.Referring to FIGS. 1 and 5, there is shown, located on the right side ofthe indicator mechanism, a side frame 141, on which is mounted thethree-level rotary switch RS1. Located on the peripheral surface of theswitch are a series of contacts 142, which, as will be explained morefully hereinafter, are connected to each of the contacts of the readoutswitches RS2-RS10 inclusive located in the parent machine. Mountedadjacent the rotary switch is a cam shaft 143, rotatably supported bythe support frame 72. Mounted on the cam shaft 143 are three cams, 144,145, and 170, which control the operation of theswitches SC3, SC2, andSC4, respectively. 'Coacting with thecam 144 is a cam roller 146 mountedon the end of a switch blade 147 of the normally open switch SC3. Asimilar roller 148 is mounted on the blade 149 of the normally openswitch SC2. The normally closed switch SC4 has a roller 172 mounted onthe blade 173. The switches 8C2, 3C3, and SC4 are mounted on brackets150, which are secured to the support frame 72 by the screws 151.Rotation of the cam shaft 143 actuates each of the switches SC2, SC3,and SC4, depending on the configuration of its associated cam, in amanner well known in the art.

Mounted on the cam shaft 143 adjacent the switch RS1 is a control drivegear 152 (FIG. 5), which is driven by a pinion gear 153 mounted on theindicator drive shaft 71. The gears are so constructed that tworevolutions of the pinion gear 153 drive the control gear 152 and thecam shaft 143 through one revolution. As shown in FIG. 1, mountedadjacent the gear 152 is a similar control drive gear 154 mounted on thewiper (not shown) of the rotary switch RS1, the wiper being of standardconstruction and driven by the pinion gear 153 through one revolution inthe same manner as described above. During each revolution of the driveshaft 71, the contacts 142 on each level of the switch are sensed by thewlper.

The three levels of the rotary control switch RS1 are represented inFIG. 8 as RSlA, RSlB, and RSlC. The contacts 142 of the various levelsare connected to similar contacts of the readout switches RSZ-RSIOinclusive in the manner shown in FIG. 8. Referring to FIG. 7, it is seenthat, as the indicator drive shaft 71 completes its first revolution,the normally open switch SC3 closes and the switch SC4 begins to close.This closing of the switch SC3 supplies an energizing pulse to the wiperof the switch level RSIC (FIG. 8) from the rectifier 133 over the loadresistor R1, the conductor 171 to the switch $03. This pulse is sent toeach of the contacts representing the numeral nine of the readoutswitches RS2-RS10 at the end of the first revolution of the shaft 71.This pulse 7. continues until the wiper of the rotary switch RS1 haspassed the zero position. By this time, the cam switch 504 has closed,thereby providing an energizing pulse to the levels RSllA and RSlB overthe closed switch 8C3. Switch level RSIA provides contacts for the oddnumerals, 1, 3, 5, and 7, while the switch level RSZlB provides contactsfor the even numerals, 2, 4, 6, and 8.

As shown in FIG. 8, each of the contacts 142 of the switch levels iswired over two positions to provide sufficient time for the energizationof the appropriate solenoid 127 (FIGS. 3 and 4). The solenoids 127 ofeach indicator assembly are represented in FIG. 8 by the designationL2Llt inclusive. Depending on the position of the wiper of the readoutswitches RS2RS10, its associated solenoids 12.7 will be energized tostop the indicator blank 12b in a position to display the appropriatecharacters corresponding to the position of the wiper in a mannerdescribed previously. As the stop pawl 125 is moved into engagement withits associated stop plate 122 upon the energization of the solenoid 127,the holding switch 163 closes, providing an alternate energizing circuitto the solenoid 127 from the rectifier 133 over the conductor 178, theclosed switch 803, the conductor 174, and the holding switch 163 to theappropriate solenoid LZ-Lltt). The resistor R3, connected across theswitch SC3, eliminates any residual magnetism in the solenoids L2L1tlupon the subsequent opening of the switch SC3 at the end of the secondrevolution of the indicator drive shaft, thus facilitating the openingof the holding switches 163. The resistor R2 and the capacitor C2suppress any spark across SC3 during its operation. Thus, at the end ofthe second revolution of the indicator drive shaft, the selectedindicator blanks will be set to indicate the amount set up in thereadout switches of the parent machine.

Referring again to FIG. 7, it is seen that, at the beginning of thesecond revolution of the indicator drive shaft, the normally closed camswitch SC2 begins to open. When this occurs, the clutch control solenoidL1 is deenergized, thereby releasing the control pawl 88 (FIG. 2) to theaction of the spring 103, thus preparing for the disengagement of theindicator drive shaft 71 from the motor drive at the end of the secondrevolution of the drive shaft 71. This insures that the drive shaft Willbe rotated only through two revolutions.

At the end of the second revolution of the drive shaft, as shown in FIG.7, the wiper of the rotary switch RS1 has completed the sensing of allof the contacts of the levels of the rotary switch, the cam switch 8C3has opened, thereby de-energizing each of the actuated solenoids 127,the indicator drive shaft is in the home position, the clutch solenoidL1 is tie-energized, the cam switch 8C2 is in an open position, the camswitch 804 is in its closed position, and the unit is in the homeposition ready for its next operation.

While the form of the invention shown and described herein is admirablyadapted to fulfill the objects primarily stated, it is to be understoodthat it is not intended to confine the invention to the one form orembodiment disclosed herein, for it is susceptible of embodiment invarious other forms.
